I’m glad to let you know that the Indonesian language pack for Mambo 4.5.1 is already available for public download on my site and on the Indonesian Translation Project on MamboForge.net. Please get your copy over there. 🙂
As I wanted to make this work more coordinate, I already opened a project page on MamboForge.net, which I call it, “Indonesian Translation Project”. The main purpose of this project is to provide the Indonesian users an appropriate language pack for their websites. At the moment, only the core packs are available. But, in the future there will be some language packs for components and modules as well. Of course, any help of yours would be appreciated. If you are able to speak and write Indonesian properly, I encourage you to join this project. Please let me know, if you are interested about it.
